Wii probably had a better launch line-up than Gamecube's entire library.

Not getting this love for the Wii's launch lineup AT ALL. It was literally all garbage except for Wii Sports, and TP (which wasn't even exclusive!) Red Steel and Trauma Center: Second Opinion were the only other games worth mentioning, and hardly.

Wii U's launch lineup was far superior overall with 3 good exclusives (NSMBU, Nintendo Land, Zombi U), 3 good eShop titles (Nano Assault Neo, Trine 2: Director's Cut, Mighty Switch Force! Hyper Drive Edition), and near a dozen good third party titles and "deluxe edition" versions of some great ones that hadn't come to Wii (Mass Effect 3, Batman Arkham City, Darksiders II).

But GCN is easily the best counting Pikmin and Melee (which launched a mere 2 weeks later), especially since there were a whopping 4 other very good exclusives (Luigi's Mansion, Super Monkey Ball, Rouge Squadron II, and Wave Race: Blue Ocean). Ironically the only other console to ever come close to that great of an exclusives launch lineup was the original Xbox the same year with Halo, DOA3, Project Gotham Racing, Amped, and Oddworld: Munch's Oddysee. We just don't get launches like those 2 anymore.

Pikmin is the only game of the GCN launch that really impresses me, and it still falls short of Twilight Princess in my book. And Wii's lineup wasn't all garbage outside of WS and TP: Excite Truck was pretty sweet.

SNES. SMW, F-Zero, Pilotwings, Gradius III, Castlevania IV, Final Fantasy IV. Seriously, nothing can compare with that.

Wii was pretty impressive too, as far as being ground breaking goes. And N64 had some doozies with SM64 and SotE.

Wii U easy but most Nintendo fans don't like 3rd party games

I liked Shadows of the Empire but man, that game had some problems!  The music was like 10 second loops and the control was so damn slippery.  That train stage was so frustrating for me.  I don't consider it a launch game, either.  I don't regret buying it but it's not what I'd consider a good game.  

Oh it was major flawed.  I just remember never seeing anything like it in terms of graphics and atmosphere.  I hated the controls of most N64 games after having mastered gamepad functions over two generations.

N64, just because of the masterpeice that was Super Mario 64

I remember walking down to my store on 1/3/97. They had 3 N64 consoles in stock with 3 games available - Mario 64, Pilotwings 64 and Wave Race. Turok and Blast Corps came about 2 weeks later. It sounds shit but the games were sooooooo good..... Best launch ever!
